Denver Roofing: Article About Preventing Ice Dams From Forming
For homeowners who live in colder climates like Colorado, ice dams can be a major roofing dilemma during the winters. Ice dams typically form along the edges of the roof, because the eaves are exposed to colder air. They can prevent snow accumulation from properly draining off of the roof whenever it begins to melt, which can cause excessive water pooling that leads to the development of leaks. This can cause major water damage to the interior insulation, ceilings and walls. Denver Roofing professionals understand how much of a nuisance ice dams can be, and that while they might seem like a relatively minor problem, they can actually lead to major roofing damage.
Three conditions must be present in order for ice dames to develop: snow accumulation, heat loss that escapes through the roof and freezing temperatures. Whenever heat escapes from the roof, it causes the accumulated snow to begin to melt. As the water travels to the eaves, the freezing outside temperatures cause it to refreeze, which creates an ice dam.
Heat loss from inside the home is not the only cause of the snow melting; it can also occur whenever the roof is exposed to direct sunlight. Temperatures do not have to be too high for this to happen. As soon as the temperatures reach above freezing, the development of ice dams is probable.
A roofing contractor from All Around roofing of Denver CO can answer any questions you have about flat roof systems or insulation.
The problems associated with ice dams are numerous. If left unchecked, they can lead to rotting of the roof deck and the interior walls. Moisture on the ceilings and drywall can create an ideal scenario for mold and mildew growth, which can cause respiratory complications for the home's residents. If the water from the melted snow reaches the insulation, it can allow even more heat to escape, which can lead to more ice dams being formed.
Fortunately, there are a few things roofing contractors can do to reduce the development of ice dams. One of the most important steps contractors might take is to ensure that the attic is properly sealed, and that there is enough insulation to prevent heat loss. They will check the exhaust systems that are located close to the top of the ridge, because these areas are prone to featuring higher temperatures than the rest of the roofing components. They can also cause snow to melt.
Whenever homeowners notice heavy snow accumulation on their roofs, while it is important to remove it as quickly as possible, it can be very unsafe to walk on top of the roof in order to clear it. Homeowners are encouraged to only remove snow and ice with a roof rake.
